Preserve provenance
Source, time, units and version.
Methodology
For each hypothesis, the system retains sources and shows a possible association, alternative explanations and missing data.
A normalised value with a source and time.
An observation that can be tested.
Rationale, alternatives and missing data.
The doctor's clinical decision and responsibility.
Six steps
If data is insufficient or contradictory, the system does not produce a definitive statement.
Source, time, units and version.
Names and units are mapped to reference vocabularies.
Only data needed for the task and permitted for analysis.
Supporting evidence, contradictions and gaps.
Policy, wording and clinical limits.
The doctor confirms, refines or rejects it.
Hypothesis structure
Uncertainty cannot be reduced to a single number.
This is a direction for investigation, not a diagnosis or a reason to change treatment on your own.
Sources
Version and applicability are stored with the claim.
Limits
Defining the scope of use is part of safety.
A BIOS result does not replace an examination, diagnostic assessment or a medical professional's opinion.
The system must not be used to stop, start or change treatment on your own.
When facts are insufficient, identifying the gap and stopping the analysis is an acceptable result.
BIOS readiness criteria are publicly available.
